Author: 1989-08-02 Unknown

History:

2008-01-14 Janet Barret - Imported into Isis3 from Isis2.

2008-03-07 Janet Barrett - Moved variables and related methods that pertain to Hapke specific parameters to the PhotoModel class.

2008-06-18 Stuart Sides - Fixed doc error

2008-10-17 Steven Lambright - Changed inheritance, moved HapkeHen specific methods into this class from the base class.

2008-11-05 Jeannie Walldren - Added documentation from Isis2 files

2012-10-15 Janet Barrett - Shortened the ZEROB0STANDARD parameter name to ZEROB0ST. This was done so that the GUI interface does not have to be resized every time it is opened. The shortened name helps to keep the parameters within the default GUI size when it is first opened. References #453. Fixes #1288.

2016-08-28 Kelvin Rodriguez - SetPhoto0B0Standard now uses QString. Part of porting to OS X 10.11
